Hello, I have been trying to diagnose a no video scenario with one of my xbox that I originally thought was being caused strictly by a bad bios flash. I original posted some questions about it in flashing and bios forums, troubleshooting has lead me to believe that my main problem is now related to eeprom issue so I figured post should be here, as it is no longer relevant to those forums if that is incorrect and I should of just continued posting in one of those previous thread I apologize... This xbox originally had a dead hard drive so I tried to read the eeprom with ch341a and a test clip. Being 1.0 xbox there was not much room to fit the test clip and after many failed attempts I gave up with the clip. At this point I unsoldered the eeprom and read it directly on the reader, I obtained good read with no issues then resoldered the eeprom. I continued to flash the tsop with xblast and upgrade the ram to 128mb. ram test passed with no issues after many heat cycles. I proceeded to flash a new bios to the tsop, except I bumped the power at the end of the procedure got an incomplete flash with frag. I was able to test some of the other sections of the tsop with recommended 3 wire trick and the xbox would boot but with flashing green and no video. I tried bypassing tsop with Aladdin but again no video and flashing green. Thinking I corrupted the eeprom I desoldered the eeprom and verified contents match the backup, and resoldered the eprom. The last modchip I tried was xblast modded Aladdin and to my surprise the xbox boots with video like normal, I believe this bios is working because it is Cromwell/Gentoox based and is ignoring the eeprom. In looking at the eeprom, I can read and write the chip no problem off board but I cannot read/write it in circuit through lpc header.... when I hook up programmer through lpc I get a red light on the programmer indicating incorrect pin or short. I now think I must of shorted something out when fighting with the test clip originally. Anyone have any idea on what I might of fried or what area I should start looking? is there any motherboard schematics floating around? I'm not ready to banish this poor box to the parts bin yet if I can help it lol. again thank to all that have helped me.
